' 6 Claims.

This invention relates to articles of out-door furniture, and more particularly to an interlocking pre-cast bench adapted to support a panel suitably aiiixed.

An object of this invention is to provide a precast interlocking concrete bench which is made Still further objects of this invention reside in the provision of a pre-cast interlocking concrete bench that is strong, durable, highly efli cient in operation, simple in construction and manufacture, and which is relatively inexpen- S1Ve.

by way of example only, wherein:

Figure 1 is a front elevational view of the the present invention, parts Figure 2 is a side elevational view of the device comprising the present invention;

Figure 3 is a vertical sectional view as taken along line 3-3 in Figure 1;

Figure 4 is an enlarged horizontal sectional view as taken along line 4-4 in Figure 1;

Figure 5 is a partial vertical sectional detail as taken along line 5-5 in Figure 2;

Figure 6 is an enlarged sectional detail showtion of Springs, La., asslgnor Inc., Denham Louisiana 12 and ll of suitable configuration. Suitable countersunk screws l6 secure a bar I 8 in abutting engagement with the buttresses. Positioned on buttresses. p

A back member 34 is provided which has an overhanging lip 36 for engagement with the upper edge of the buttresses l2 and M. Further,

gagement with the buttresses Figure 8, suitable gaps 60 are formed in the projecting tongues 26 and 28 in order that the seat member 29 may be readily interlocked with the bar l8, thus insuring a substantially rigid construction.

Since, from the foregoing, the construction and advantages of this interlocking pre-c'ast concrete bench can be readily understood, further description is believed to be unnecessary.

However, since numerous modifications will readily occur to those skilled in the. art aiter a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the precise embodiment shown and described but all suitable modifications and equivalents may be readily resorted to which fall within the scope of the appended claims.

Having described the invention, "what is claimed as new is:

l. A precast concrete bench comprising arpair of substantially parallel spaced concrete buttresses, a bar secured to and abutting said buttresses and extending therebetween, a reinforced concrete seat forming slab having pairs of spaced parallel projecting tongues depending therefrom positioned on said buttresses, said projecting tongues straddling said buttresses, certain of said tongues having gaps formed therein receiving the ends of said bar, a back forming slab secured to said buttresses and binding means between said tongues and said buttresses.

2. A'precast concrete bench comprising a pair of substantially parallel spaced reinforced concrete buttresses, a bar secured to said buttresses and extending therebetween, a seat forming slab having substantially aligned parallel projecting tongues depending therefrom positioned on said buttresses, said projecting tongues straddling said buttresses, said tongues having gaps formed therein receiving the ends of said bar, said tongues and said buttresses having aligned mortar grooves, mortar in said grooves and locking said tongues to said buttresses, and aback form- '3.
